Question is, although the Mint Team won't support LMDE2 after January 2019, will it be possible for my LDME2 MATE installation to have security updates (it can be directly from Debian)?
Will this happen without the need for me to change configurations, or what will I have to tweak for this to happen?

I'm asking this because I have a 32 bits LMDE2 MATE with no upgrade to LMDE3 available. I hardly use this machine and I don't want to have the huge amount of work configuring this system for the little time I'll be using it...
